    Imazethapyr belongs to imidazolinones selective pre-emergence and post-emergence herbicides, being the branched-chain amino acid synthesis inhibitors. It is absorbed through the roots and leaves and conducts in the xylem and phloem and accumulates in the plant meristem, affecting the biosynthesis of valine, leucine and isoleucine, destroying the protein and killing the plant. Pre-mixing it with soil for treatment before sowing, applying soil surface treatment before emergence and early post-emergence application can control many grasses and broad-leaved weeds. Soybean has resistance; the general amount is 140 ~ 280g / hm2; it has also been reported of using 75 ~ 100g / hm2 in soybean field for soil treatment. It is also selective for other legume at a dosage of 36 ~ 140g / hm2. If using a dose of 36 ~ 142 g/ hm2, either mixing with soil or early post-emergence spraying, can effectively control two-color sorghum, westerly, amaranth, mandala and so on; the dose of 100 ~ 125g / hm2, when mixed with soil or pre-treated before emergence, have excellent control effect on the barnyard grass, millet, setaria viridis, hemp, amaranthus retroflexus and goosefoots. Post-treatment can control annual grass weeds and broad-leaved weeds with the required dose of 200 ~ 250g / hm2.

    Selectively pre-emergence and early post-emergence soybean crop herbicide, which can effectively prevent the amaranth, Polygonum, Abutilonum, Solanum, Xanthium, Setaria, Crabgrass and other weeds.
